+/*?
+ * Tag: vmur.1
+ * Text: "The %s cannot be loaded without z/VM"
+ * Severity: Error
+ * Parameter:
+ *   @1: z/VM virtual unit record device driver
+ * Description:
+ * The z/VM virtual unit record device driver provides Linux with access to
+ * z/VM virtual unit record devices like punch card readers, card punches, and
+ * line printers. On Linux instances that run in environments other than the
+ * z/VM hypervisor, the device driver does not provide any useful function and
+ * the corresponding vmur module cannot be loaded.
+ * User action:
+ * Load the vmur module only on Linux instances that run as guest operating
+ * systems of the z/VM hypervisor. If the z/VM virtual unit record device
+ * has been compiled into the kernel, ignore this message.
+ */

+/*?
+ * Tag: vmur.2
+ * Text: "Kernel function alloc_chrdev_region failed with error code %d"
+ * Severity: Error
+ * Parameter:
+ *   @1: error code according to errno definitions
+ * Description:
+ * The z/VM virtual unit record device driver (vmur) needs to register a range
+ * of character device minor numbers from 0x0000 to 0xffff.
+ * This registration failed, probably because of memory constraints.
+ * User action:
+ * Free some memory and reload the vmur module. If the z/VM virtual unit
+ * record device driver has been compiled into the kernel reboot Linux.
+ * Consider assigning more memory to your LPAR or z/VM guest virtual machine.
